IMPROVEMENT m rnsmANnFAcfrunsoF BJLLlAR D-BALLSAND OTHER COMPOSITIONARTICLES.

mflohsdflenfarsdtolnthssemljstmtaudmafingpsrtof mm I all whom mayconcern.-

Be'it known tbatwe, Lnwrs DEIT BENJ MIN P. WAYNE, and ,ALBBBN Srom, ofthe city' and county of Albany and State of New York, have invented anew and improved Method of Manufacturing Billiard-Balls, of which thefollowing is a specificat-ion, reference being had to the annexeddrawing, in which--- A is the composition-ball; B is the coatingoftin-foil; and

O is the outer or collodion coat.

To understand fully the nature and objects of .our invention, it will benecessary to describe briefly the mode of constructing billiard-ballsand other articles of various shapes, of a suitable molding-composition.

The molding-composition used is made by grinding paper to a very fineflock, or otherwise reducing any kind of fibrous, vegetable, animal, ormineral matter to agvery finestate.

With paper-pulp or flock, or other finely-commiouted fibrous substance,is used gum shellac or any other solid, fusible, and adhesive gum, whichis likewise redncedto avery fine powder.

This cement; is thoroughly intermixed with the fibrous substance, bothbeing in as dry a state as pos:

sible. I

In the process of molding this composition, heat and pressure areapplied simultaneously, the former to fuse the shellac used inthecompound, to cause it to cement the small fibers together 'and formasolid homogeneous body, and the latter "to compress and pack togetherthe fibers throughout the mass,thns

l producing a very dense body.

The specific gravity of the billiard-balls or other articles made of theabove-described composition may be increased by the addition of whitelead or any other suitable pigment, which is added to the composition ina dry and pulverized state.

Whereas billiard-balls made of the above-described.v

composition cannot be shitably colored, and are notcapable of receivingand retaining a. line polish, and do not present the appearance. of1vory,-it became necessary to coat them with a substance that-could betnrnd true and polished, and that might also be colored, as desired.

It was found that collodion was the, best substance,

known for this purpose. It was also found, upon trial, that compositionbilliard-balls'coated with collodiou did not retain their shape anddensity; that they soon became useless on account o'f theaillinity'ofthe shellac in the composition and the alcohol in thecollodion.

To prevent this destructive action from taking place, the softening ofthe shellac isthe object of our invention. 7

We take theiuner or composition-ball Aand cover it with a coating oftin-foil or other metal. Said By the interposition of a metallic coat orlining, B,

there can be no action of the alcoholpr other solvent of the collodionupon the shellac or other adhesive gum used in the inner orcomposition-ball A.

Billiard-balls constructed with a tin-foil or metallic lining, B,interposed as herein shown and described, have proved to be in allrespects superior to any composition or imitation of ivory ballsheretofore known. We do not-confine ourselves in the use of the in-.

terposed lining or coatof tin-foil to billiarddaalls, as

it can he used with advantage on allarticlcs similarly made.

The interposed lining B may be used between any composition containingadhesive gums that may be acted upon by. the solvents used in thecollodion We claim as our invention- The coating or lining B, oftin-foil or other similar substance, between the composition-ball -Aand'the collodion coating 0 of a billiard-ball, in the manner,

and 'for the purpose hereinb'eforc set forth.
